'Nope' to which part of my statement or both parts?


Nope it doesn't use quench timing.

To Tech support,

The RP cube has both outputs, a 3.5mm and a RJ11 if recall correctly.


So there is. That side of the cube was harder to find an image of.

Anyhow, speedlites are operated via gate timing at the same voltage, Alien Bees are power adjusted by voltage variation.

Looks like a job for a 555 timer voltage-to-pulse duration converter with a start trigger.
Use the redundant model light core as VCC, and the sync as trigger, then the reference voltage determines the time duration before the quench is switched.

Its seems do-able.

Bingo. That's why I need the storage scope so I can find out what the JrX is using for base timings which work fine for Nikon flashes.

Cost in parts if you add it to the CSRB+ would be less than $10 probably. Cost to do an external version w/ case, board, batteries, shipping, packaging, etc. would probably be at least $80 to not lose your shirt on it from labor/parts/shipping costs. I'd like to see it added to the CSRB+ circuitry and they can sell it as a CSRSB+ because it makes the most sense...would require replacing the mono socket w/ a stereo 3.5mm socket but everything else is inside except for the 555 timer circuit...

Please do share anything you're willing to share. I'm definitely capable of assembling things like this (due to many other projects at work over the years), I just don't have the know how to design it. Wish I had a scope to send you Ken ;)

Glad to see it seems we're close to having a solution. The new Canon flash system is making me even more jealous to boot. Hope a solution can come out of this discussion for all of our hybrid systems. And that incidentally is still an innovative product...only pocket wizards can do that but they don't have the nice CyberCommander. PCB...you're close to having an even better CyberSync system ;)

Fingers crossed and keep up the good work!

Marc

I dont want to assume the context of your own mix and match issue.

So I'll describe my own.

I'd like to mix Einsteins and SB800's and control both from camera. This is how I intend to go about it.

I'll use the cybercommander to set the einsteins remotely, and the use a SU800 to control and trigger the SB800's. I would then use a CST attached to one of the SB800s' sync port which will simultaneously trigger the Einsteins.
I suppose the SU800, could be substituted by radiopoppers or equivalent.

I'm not sure how I'll go about using the CC as a meter per light though. I'll probably just take out the CST and point it at the respective SB800.

No need...did manage to find one to use for half an hour :)
What I haven't been able to figure out is why the pulses coming out of the radiopopper jrx's 3.5mm port are only 100mV. I would have expected higher voltage, but I think my problem is I'm thinking of this as digital instead of all analog. The sync pulse out of the CSRB+'s RJ11 connector is also a weird -8V.

I doubt the new Canon flashes would work w/ this...they probably yanked out the quench signal like Nikon did w/ their SB9xx series...

Just checking in here since after all these months, I'm still in the position of constantly wishing this was possible. Curious to see if anything useful was discovered.

Here's to hoping...

Sounded like phil was going to work on it so I didn't do anything except some minor research on parts to use (and I got put on the project from hell the past few months so I haven't had much time to do anything)-:
A hint or two from the PCB folks about how the "fire" pulse works on the RJ11 would have been helpful ;-)

Asking us to tell you how to hack an Einstein remote control is about like asking Apple to divulge their operating system. You're just not going to accomplish it with a simple circuit. There are many complex algorithms involved.
